Sensational pictures have captured the moment a Siberian roofer and his friend scaled to the top of the world’s second highest building.

Taken from a video, which is not for the feint-hearted, they show Vadim Makhorov, from Novosibirsk, and fellow roofer Vitaly Raskalov, from Ukraine, climbing up the 115-storey Ping An International Finance Centre in Shenzhen, China.

Clambering up ladders and over girders, when they reach the summit of the 660metre-tall skyscraper they even manage to get onto the crane perched on top and pose on the end of the beams. Still being built, it will be the second tallest tower on the planet after the famous Burj Khalifa in Dubai when it opens next year.

The daredevil climb comes a year after the pair last made headlines around the world, by scaling to the top of the 600metre-tall Shanghai Tower in China.

In a post on his blog, Vadim, 25, said: 'Just over a year ago, we climbed to the Shanghai Tower and this caused an incredible response that, frankly, we did not expect. We decided to support this glorious tradition and conquer all new construction projects around the world.

'This time we prepared more carefully, as some guys tried to conquer the skyscraper before us and not all of them were successful. We assumed that this time the security of the new building would guess that there are Europeans who would gladly want to climb it and make a video about it.

'The security did not want to lose their jobs, and were more alert, but it was not enough to stop us.' He added: 'It was easier than with the Shanghai Tower as we did not have to sleep on the construction site for almost 18 hours, but nevertheless, it was very cool.'

The roofers filmed their adventure as they climbed a wall and sneaked into the building site before making their way up a staircase.

Breath-taking footage shows them looking out windows and looking over the edge as they edge their way higher into the sky. At one point they reach a ladder and are seen shaking it to ensure it is safe before climbing higher. They are also seen sitting with their legs dangling over the edge, with the people on the ground far below looking like ants.

The pair, who have climbed many other structures including the Great Pyramid of Giza, have a legion of fans following them on the Internet.

On their YouTube channel, a fan called Irving Bisman writes: 'They’re Russian, and the amount of crazy stuff that happens there is insane itself. I bet not even the French 'Spiderman' can do this.'

Last year the roofers became web sensations after the video of them climbing up the Shanghai Tower was used in a new advert for Google. At one point on the ascent they stopped and examined a gap in a hand-rail that could have resulted in them falling to their deaths.

Millions of people viewed the online commercial – which promotes the 'OK Google' application for mobile phones - on the Google Russia channel.

Entitled 'How you can use your voice at an altitude of 632 metres', it demonstrates how the American-based search engine can be used in any place, at any time.

During the video, Makhorov is shown asking the height of the building in a voice command to Google. He then jokes: 'Mama will be shocked. I hope she will not see this video.'
